Abstract
In sub-Saharan Africa, more than 40% of children under five years of age suffer from
vitamin A deficiency. Among several interventions in place to address vitamin A
deficiency is biofortification, breeding vitamin A into key staple crops. Staple crops
biofortified with beta-carotene, the precursor to vitamin A, are orange in color. Given the
natural occurrence of high levels of beta-carotene in many sweet potato varieties,
breeding progress for biofortified orange sweet potato (OSP) has been much faster than
for the other vitamin A enhanced staples. Nearly 3 million households have been reached
with OSP. This paper reviews key factors influencing the uptake of OSP, the breeding
investment, five key delivery approaches that have been tested in the region and efforts
to broaden government and other stakeholder engagement.
